| Abstract: | Introduced the concepts of Digital Valley and Virtual Reality in the digital engineering in the 21st century. Researched many pivotal technologies of Virtual Reality which were used to build the Digital Valley: the technology of LOD and LADBMS to improve the efficiency of the graphical system, the technology of multi-dimension human-computer interaction to build friendly interface between the system and users, the model of the valley and the application of 3S data in the digital valley. Discussed the ways the Virtual Reality apply to Digital Valley: 3D browsing, adding the results of simulation, fighting flood, encouraging travel in the valley and so on. |
